Van Hove's “lambda^2 t” limiting procedure is analyzed in some interesting quantum theoretical cases, both in non-relativistic and relativistic models. We look at the deviations from a purely exponential behavior in a decay process and discuss the subtle issues of state preparation and initial time.

Abstract
Van Hove's “lambda^2 t” limiting procedure is analyzed in some interesting quantum theoretical cases, both in non-relativistic and relativistic models. We look at the deviations from a purely exponential behavior in a decay process and discuss the subtle issues of state preparation and initial time.File in questo prodotto:
